The United States says it remains concerned about political activist, Itai Dzamara’s whereabouts and wellbeing.

In a statement Thursday to remember his alleged abduction a month ago, the U.S Embassy in Harare said, “On this date, we reiterate our call to the Zimbabwean authorities to mobilize their full resources to investigate the circumstances surrounding Mr. Dzamara’s abduction and to ensure the protection of his fundamental human rights and freedoms.

“The United States stands together with Mr. Dzamara and the people of Zimbabwe in supporting their right to freedom of expression and peaceful assembly. We call for Mr. Dzamara’s immediate and safe return to his family and friends.”

Dzamara was allegedly abducted a month ago by state security agents and has not yet been found despite a court order for the national spy agency, the Central Intelligence Organization (CIO), the police and related security bodies to look for him.

Dzamara’s Occupy Africa Unity Square has been calling for the resignation of President Robert Mugabe they accuse of running down Zimbabwe, once considered the jewel of Africa.

His colleagues have also reported that they are being followed by unidentified people, suspected to be CIO agents, who at times park vehicles without national registration numbers outside their homes
